Absorbent article fastening device

ABSTRACT

A dual fastening device suitable for pull-up and cinch use with absorbent articles. The fastening device preferably includes a first fastening member and a second member.

FIELD OF THE INVENTION

[0001] The present invention relates to an improved fastening device forabsorbent articles such as diapers, training pants, and pull-ups. Moreparticularly, the present invention relates to improved fasteners forjoining the front of a disposable absorbent article to the rear of thearticle with an improved combination of application ease and fit.

BACKGROUND OF THE INVENTION

[0002] Conventional absorbent articles, such as disposable diapers andtraining pants have typically employed adhesive or mechanical fastenerswhich attach appointed waistband sections of the articles around awearer's waist. In addition, various configurations of waist elastics,leg elastics, and elasticized outercovers have been used on absorbentarticles to help produce and maintain the article about the bodycontours of the wearer.

[0003] Conventional absorbent articles, such as those described above,have not provided desired levels of reliable fit, and have beensusceptible to excessive sagging and drooping during wearing. Thearticles have not adequately maintained the desired levels of fit,comfort and ease of use. Where the garment has been constructed withmore aggressive fasteners to better maintain the desired fit,undesirable skin marking and/or a difficult to remove article mayresult. As a result, there has been a continued need for garments havingmore consistent fit, greater resistance to sagging and drooping, andgreater ease in the application and removal of the article. Accordingly,it is an object of the present invention to provide an improved articlefastening device.

SUMMARY OF THE INVENTION

[0004] An absorbent article having a first waist region, a second waistregion and a crotch region. The crotch region interconnects the firstwaist region and second waist region. The absorbent article includes anarticle inner surface, an article outer surface a topsheet, a backsheet,and an absorbent core interposed between the topsheet and the backsheetand a fastening device. The fastening device joins at least a portion ofthe first waist region with at least a portion of the second waistregion. The fastening device includes at least one first fasteningmember, and at least one second fastening member. The first fasteningmember is joined to the first waist region. The first fastening memberincludes at least one first tab. The first tab includes a first tabinner surface, a first tab outer surface, and a first tab fasteningelement on the first tab inner surface, and at least one second tab. Thesecond tab includes a second tab inner surface, a second tab outersurface, and a second tab fastening element on the second tab innersurface. The fastening device is designed to allow an article user tohold one element of the fastening device such as the first tab, andconnect the first and second waist regions in at least two places. Thisis achieved through manipulation of bond strengths between the fasteningdevice elements. The fastening device includes means for providing areleasable combined tab fastening bond strength between the first tabouter surface and the second tab inner surface. A second fasteningmember is joined to the second waist region on the article outer surfaceand includes at least one attachment landing zone. Each first tabfastening element and second tab fastening element are configured toprovide an operably secure, fastening engagement with the attachmentlanding zone. The fastening device may include at least one storedlanding zone on the article inner surface and means for providing areleasable storage fastening bond strength between the stored landingzone and the first fastening member. The releasable storage fasteningbond strength may be less than the releasable combined tab fasteningbond strength. The fastening device may include a means for providing afirst releasable fastening bond strength between the first tab fasteningelement and the attachment landing zone that is stronger than the meansfor providing the releasable combined tab fastening bond strength. Ameans for providing a second releasable fastening bond strength betweenthe second tab fastening element and the attachment landing zone may begreater than or equal to the means for providing the first releasablefastening bond strength.

[0044] The first fastening member 42 is designed to be joined to thefirst waist region 36 as shown in FIG. 1. The first fastening member 42may be joined, operably connected, or attached to the first waist region36 in any fashion known in the art. The first fastening member 42 may beof any size and/or shape and may be made from any suitable material. Thefirst fastening member 42 may optionally form an extension from thefirst waist region 36 in the traverse axis 110 direction. Any portion ofthe first fastening member 42 may be elastic, inelastic, extensible, ornon-extensible. Preferably, the direction of elasticity or extensibilityis in the traverse axis 110 directions. The first fastening member 42may be composed of any suitable materials known in the art. For example,the first fastening member 42 material may be composed of a film or anonwoven including a spunbonded nonwoven fabric, aspunbond-meltblown-spunbond fabric, a neck-bonded-laminate fabricmaterial, a stretch-bonded-laminate fabric material or the like, as wellas combinations thereof as know to those skilled in the art. The firstfastening member 42 may include at least one first tab 51 and at leastone second tab 61.

[0045] The first fastening member 42 is shown on the left side of FIG. 1in a stored position. The first fastening member 42 is shown on theright side of FIG. 1 is not stored and extended outward in thetransverse 110 direction. The first fastening member 42 is preferablystored for shipping and storage. The storage design configuration isdesigned to decrease storage space requirements and protect thefastening device from inadvertent damage. A first tab width 66 and asecond tab width 56 are shown in FIG. 1.

[0046]FIG. 3 is an exploded side view of the first fastening member 42when in a stored condition.

As shown in FIG. 3, the first tab 51 includes afirst tab inner surface 52, a first tab outer surface 53, a first tabfastening element 54, and a first tab length 55. The first tab outersurface 53 is the side opposite the first tab inner surface 52 and isgenerally the side away from the viewer in FIG. 1. The first tab innersurface 52 corresponds to the surface facing the viewer in FIG. 1 andgenerally corresponds to the article inner surface 271. A side view ofthe surfaces is shown in FIG. 3. The first tab fastening element 54 isjoined to the first tab inner surface 52 as shown in FIG. 3. The firsttab fastening element 54 may include any fastening element known in theart including adhesives, cohesives, hook materials, loop materials,snaps, buttons, tabs, slots, magnets and combinations thereof. The firsttab fastening element 54 may have any shape such as a circle, square,rectangle or triangle.

[0047] As shown in FIG. 3, the second tab 61 includes a second tab innersurface 62, a second tab outer surface 63, a second tab fasteningelement 64, and a second tab length 65. The second tab inner surface 62corresponds to the surface facing the viewer in FIG. 1, a portion ofwhich can be seen in FIG. 1, outward along the traverse axis 110 fromthe first tab 51. In FIG. 1 and in FIG. 2, the unstored first fasteningmember 42 has at least a portion of the remaining second tab innersurface 52 disposed under the first tab 51. The second tab outer surface63 is the side opposite the second tab inner surface 62 and is generallythe side away from the viewer in FIG. 1 and is shown in FIG. 3. Thesecond tab fastening element 64 is joined to the second tab innersurface 62 as shown in FIG. 3. The second tab fastening element 64 mayinclude any fastening element known in the art including adhesives,cohesives, hook materials, loop materials, snaps, buttons, tabs, slots,magnets and combinations thereof. The second fastening element 64 mayhave any shape such as a circle, square, rectangle or triangle.

[0048] The first tab 51 and the second tab 61 may be located anywhere inthe first waist region 36. The first tab 51 may be preferably locateddirectly under of the second tab 61 such that the first tab outersurface 53 faces the second tab inner surface 62 as shown in FIG. 3. Aside view of this arrangement is shown in FIG. 3. The first tab length55 and the second tab 65 are measured outward along the traverse axisfrom the same starting point. The starting point may be any location.One starting point may be the traverse outer most point of the backsheet26 where the tabs begin as shown in FIG. 1. The first tab length 55 maybe longer, shorter, or equal to the second tab length 65. Preferably,the first tab length 55 is shorter than the second tab length 65. Ashorter first tab length 55 may facilitate manufacturing and/or usermanipulation of the first fastening member 42.

[0049] As shown in FIG. 1, the fastening device 41 may include at leastone stored landing zone 45. The stored landing zone 45 is used to securethe first fastening member 42 in a pre use, stored location. The storedlanding zone 45 may be located on the article inner surface 271, orarticle outer surface 261 (see FIG. 2). Preferably, the stored landingzone 45 is located in the same waist region as the first fasteningmember 42. Also preferably, the stored landing zone 45 is located onthe-article inner surface 271 in the first waist region 36 inboard ofthe first fastening member 42 along the traverse axis 110 as shown inFIG. 1. The stored landing zone 45 may include plastics, adhesives,cohesives, hook materials, loop materials, snaps, buttons, tabs, slots,magnets and combinations thereof as are know to those skilled in theart. The stored landing zone 45 may have any shape such as a circle,square, rectangle or triangle.

[0050]FIG. 3 shows the first fastening member 42 in an exploded sideview when in a stored, pre-use condition. The exaggerated separation ofthe elements allows a visual representation of the releasable bondsbetween the various components. The bonds are designed to be strongenough to function as desired, but weak enough so that a user may breakthem and separate the elements at various points in the use of thearticle. The releasable bond strengths between these components aredesigned to have a preferred relationship that assists in the use of thefastening device 41. The releasable bond strengths desired may beprovided by several means.

[0051] A releasable tab to tab bond 81 is designed to act between thefirst tab 51 and the second tab 61. The releasable tab to tab bond 81may be located anywhere on the first tab 51, the second tab 61, or both.As shown in FIG. 3, the releasable tab to tab bond 81 is located on thesecond tab inner surface 62 and first tab outer surface 53.Alternatively, at least a portion of the releasable tab to tab bond 81may be on the first tab outer surface 53, the second tab fasteningelement 64, or both. The releasable tab to tab bond 81 may be created byadhesives, cohesives, hook materials, loop materials, snaps, buttons,tabs, slots, magnets and combinations thereof as are know to thoseskilled in the art. The tab to tab bond 81 may also be a mechanical bondsuch as bonds created by ultrasonic, pressure, or thermal energy. Thereleasable tab to tab bond 81 may have any shape such as a circle,square, rectangle, or triangle.

[0052] The releasable tab to tab bond 81 has a release load which is theload required to release the releasable tab to tab bond 81, allowing thefirst tab 51 and the second tab 61 to separate. The release load mayalso be referred to as bond strength. The separation is designed tooccur between the first tab outer surface 53 and the second tab innersurface 61. Generally, the release load should be measured relative tohow the fastening device 41 will normally be used and released. Thiswould suggest that the release load should be measured as a peel load atany angle out of the plane of the article inner surface 271. The peelload should be measured only once on the first release of the tab to tabbond release load since the releasable tab to tab bond 81 may bedesigned to have the strongest release load during the first release.

[0053] A releasable storage fastening bond 82 is designed to act betweenthe stored landing zone 45 and the first fastening member 42. Thereleasable storage fastening bond 82 may act between the stored landingzone 45 and the first tab fastening element 54 as shown in FIG. 3. Thereleasable storage fastening bond 82 may also be created between thestored landing zone 45 and the first tab inner surface 52, first tabfastening element 54, second tab inner surface 62, second tab fasteningelement 64, or a combination thereof.
